I can't open any of my folders by clicking or double clicking on them, none of my drives or external drives as well. It bring sup a window with the search prompt, as in how you would search a drive or search your computer from Windows. I don't have a save point to go back to an earlier time either... I can right click on start and explore and get to my files that way, but even clicking on folders not in the tree menu the search windows pops up.
I suspect you have a virus problem. First thing to do is fix the double click problem. This fix might help:
Normally when a virus infects a windows system which causes a drive opening problem, it automatically creates a file named autorun.inf in the root directory of each drive.
This autorun.inf file is a read only ,hidden and a system file and the folder option is also disabled by the virus. This is deliberately done by the virus in order to protect itself. autorun.inf initiates all the activities that the virus performs when you try to open any drive.
You have to just delete this file and restart your system to correct this problem.
Follow the set of commands below to show and delete the autorun.inf
Open Start>>Run and type cmd and press enter. This will open a command prompt window. On this command prompt window type the following steps.
type attrib -r -h -s autorun.inf
type del autorun.inf
if you have a d drive:
now type d: and press enter for d: drive partition. Now repeat steps 3 and 4. Repeat step 5 for all your hard disk partition.
Restart your system and your immediate troubles will be fixed.
